looking at some of the comments on the teacher's attitude I feel like some people have never read one of these ecchi-harem school manga before? this is going to continue mostly unchanged, occasionally adding new girls or showing some backstory exposition but never actually changing the cast dynamic until readers start getting bored of the cycle, at which point it'll get axed and make a five to ten chapter rush with a forced final arc and an open ending with some variation of "I hope these peaceful days continue"
